Catch2 is released under the terms of the Boost Software license: > Boost Software License - Version 1.0 - August 17th, 2003 > > Permission is hereby granted, free of charge, to any person or organization > obtaining a copy of the software and accompanying documentation covered by > this license (the "Software") to use, reproduce, display, distribute, > execute, and transmit the Software, and to prepare derivative works of the > Software, and to permit third-parties to whom the Software is furnished to > do so, all subject to the following: > > The copyright notices in the Software and this entire statement, including > the above license grant, this restriction and the following disclaimer, > must be included in all copies of the Software, in whole or in part, and > all derivative works of the Software, unless such copies or derivative > works are solely in the form of machine-executable object code generated by > a source language processor. > > THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR > IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, > FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT.

GNU-EFI claims to be released under the BSD license. Again, I could not find its specific license file, so I am reproducing a generic 3-clause BSD license (the most restrictive, so as not to assume any extra rights that may not actually be granted) for it here: > Copyright © Nigel Croxon > > Redistribution and use in source and binary forms, with or without > modification, are permitted provided that the following conditions are met: > > 1.

Relevant code includes license statements at the top of each file. ## Waf Popcorn's build system uses [Waf](https://waf.io/), which claims to be released under the BSD license. I could not find its specific license file, so I am reproducing a generic 3-clause BSD license (the most restrictive, so as not to assume any extra rights that may not actually be granted) for it here: > Copyright © 2005-2018 Thomas Nagy > > Redistribution and use in source and binary forms, with or without > modification, are permitted provided that the following conditions are met: > > 1.
